Overview

[Import] Add some not-yet-used functions that are prone to conflict

Before

Conflicts keep happening on these functions when I add them in 'thematic' PRs

After

The functions are there....

Technical Details

None of these are used yet

Note that there are not other functions to be shared between the Entity-specific classes - eg. Contribution_MapField Contribution_Preview Contribution_DataSource - so repeating this small function makes more sense than a trait
