As extension to formulas List and Part, can we have formulas to operate on lists?
For example, we have two text strings:
Text A: 1,2,4,5 Text B: 1,2,3
A formula to join "Text A" and "Text B" would yield:
Text C: 1,2,3,4,5
A formula to find parts of "Text B" not in "Text A" would yield:
Text D: 3
One use of these formula is to operate on RecordId concatenations. The result can be used in conjuction with "multi" type custom buttons to run actions on selected records. I am sure they can be useful in other situations.
