extrusion in subtraction of multiple profiles in a sketch

[SMALL AXE]

hello to all,I looked for from everywhere and not only in the forum cad3d, but I did not

found an answer to my problem using inventor 2010.
I would like to draw (or model) the attached piece and proceed as follows:
1-Disname the profile highlighted in blue and extrude it
2-design on each face a sketch consisting of various profiles
3-extrude each sketch (in subtraction) by selecting profile

the problem is when I have a hundred profiles inside the sketch to extrude

in subtraction on each face:I should select profile by profile and if I mistake

select I remake everything from top.
how would you proceed?
there is some alternative method to select multiple profiles inside the sketch to

can extrude them at once?

select the sketch -> share.
in this way the same sketch is usable in multiple processing

Thanks peppe for the answer, but maybe I explained badly.
I pose the problem in another way:
try to make an extrusion of a simple rectangle, draw on a face a sketch with multiple profiles (about fifty circles),
to extrude these circles by subtracting them to the solid as you would? You will select the circles one by one true?it's here my problem I wanted to know if there was another method to select all the circles at once because if not, it is really the thing is terrible.

If the sketch elements follow a logical sense you could extrude one and serialize the processing.
but if they have a random order as an image you should select one at a time

another solution is to project the face cutting edge into the sketch and extrusion instead of subtracting use intersection, you get the same result with only one selection.
I hope I've been clear and you've been helped

thanks rf.infissi for your clarification,
you are right with regard to a regular cube or solid, but if you try to make the same reasoning for an irregular solid like the one attached above, when you do the extrusion with intersection you cut the rest of the solid, and then remake the extrusion of the cut parts with condivid sketch or make independent solids do the extrusions with interseca and eventually join the whole, it is where I arrived to solve the problem

Actually you're right it would take a command to reverse the selection, but I couldn't find it.
I think there's no solution

follow the collhttp://inventortrenches.blogspot.it/2012/03/ilogic-to-select-all-of-closed-profiles.html?m=1is an ilogic rule that selects all closed profiles of a sketch at once and performs extrusion or cutting.
I didn't try but it should work.
As soon as I have a little time I try

ok I tried it and it works great if you have trouble contacting me
