list for blocks with attribute

[Mirabilio]

Good morning.
I tried to do a search inside but I didn't find what I'm looking for.
I need to create a command that runs the following functions:

- add to the selection all the blocks that contain a value within an attribute (a kind of selerapid to mean us)

Thank you for your support!
