Substitute Variables in Files Recursive - Octopus 3.1.2

How do I create a uservoice request? Not allowing variable substitution recursively seems counter-intuitive and allowing it so that it can be activated by a check box would seem to serve all needs.

I was just tripped up by it this afternoon, added a new project to my deployment but forgot to explicitly list the new folder in the list of variable substitution folders.

Looks like there is already a uservoice request, https://octopusdeploy.uservoice.com/forums/170787-general/suggestions/6261527-allow-for-wildcard-directory-searching-for-substit.
