visibility of a dynamic block containing two subblocks with relative parameters

[andr_ea3d]

Good morning to all, I hope to be in the right discussion and if not I apologize. . .
I expose my problem to you, I practically created two separate blocks with the visibility parameter, each block has lines that according to the block size are hidden, I would like to group the two blocks in the same block by being able to choose the first or second and both of the first and second I would like to keep the parameter of visibility lines... Can someone advise me how to overcome this inconvenience? now, with the visibility command, I can choose only the two blocks but nn the "subparameter" of visibility of the individual blocks...I'm going crazy and I hope to be explained. . . .
waiting for an answer I greet the staff and who can give me a useful advice

is not possible

the visible parameter is unique for each block, so you can't have more than one parameter of visibility, you can't do what you ask (sold visibility).
you can only make so many different states so you can have
block-visible' 1
block-visible' 2
block- visibility 3
blockb-visible' 1
blockb- visible 2
blockb- visible 3

but not block -> (visited 1/visited 2/visited 3)
