Are 2 sticky positions for the same item possible?

I have the top of a table of data I want to stick which works fine. However sometimes something above the player can appear on scream and that also needs to be sticky.   If that upper item is sticky then the lower item (the top of my table) still needs to be sticker but with a new deeper top value.

Is this possible?    I thought sticky.update(); may assist with this but not 100% sure.
