Best practice to re-use same query in the same BIP data model

Summary:

I have a common query say for selecting business unit based on certain user based login. Now I have a main data model query with multiple sub-queries in it. And I need to put this Common BU query at multiple points in the main data model query.

Please advise whats the best way to do it. One way is of course to just insert the common query at multiple places but that makes the main query big and not very readable.

if anyone has done this, request to please share the approach.
