Easier way to propagate several outputs

Hello,

When propagating several outputs from a function group, 

you have to right click and go to "propagate outputs" and select the outputs to propagate.

But when you have more than 10 outputs to propagate, it's very long to do it each time.

Maybe could you let the menu open, and lets us to click on all outputs we need to propagate ? and the menu close when clicking on the page

or maybe something like, allow multi click by holding CTRL key ?
