Fermata on select staves only

I know that this has been adressed in the past, but the latest I could find was from two years ago, so here goes. Is there a way to have a fermata on select staves only? Using Alt does not do it.
In the example below, I need a fermata only on the voice staff.

Best way (and save it as default as you’ll probably usz it in different projects) is to create a fermata playing technique !
