Integrating "Templates"

Hi, when we buy a template in Glide store, we’re often interested by one or x functionnalities inside it (ex. creating a Forum …).
-> It would be great to be able to copy-paste all relevant Glide-Tabs in our target app (including the “relations, lookup etc”…). Without this, the expected value of a template is not really achieved since we have to re-do everything (… if we understand how it works!)
