I think a simple reproducible example ("reprex") may be necessary for you
to get a useful reply. Questions with vague specifications such as yours
often result in going round and round with attempts to clarify what you
mean without a satisfactory answer. Clarification at the outset with a
reprex may save you and others a lot of frustration.
