Is there a way to filter pages where change has been done in the specific part of the page?

[Svetla Prahova]

We track our product requirements on pages.  All requirement pages are created from a template. Each product req. page contains 4 tables: page properties, description of the requirement written by PO, analysis of the requirement which is done from BA, and status information/comments here all (PO, BA, team) can write questions, comments and etc.

Sometimes PO changes requirement’s description in 2nd table after the requirement is analysed and under development, and if BA is not informed, he can miss it.

Is there a way to filter recently updated pages where change has been done in table 2 only? Or BA to be notified each time when text in 2nd table is changed?
