Shared Dynamic Variables for Rules

I have a few dynamic variables I use in multiple rules. Some are relatively complex to configure like "Support Team member is available (Boolean)" - made by fetching Support Teammate Group > Filter (Teammate.is_available == true) > TeammateList.length > 0

I need to re-build this variable in every rule where i need it.

It would be handy to save "shared" variables - save a dynamic variable with a static config and a description, which can be imported into multiple rules.
