Link or Mirror Rows within the Same Sheet

Hi there,

Is there a way to link cells within the same sheet? I want to mirror rows exactly:

As an example, I have my sheet divided into 2 workstreams, Finance and HR. They each have their own schedules and deliverables. Since HR Deliverable 1 (line 927) is due between Finance Deliverable 1 (923) and 2 (925) I would like line 927 to mirrored into line 924. I can't just copy and paste because it doesn't capture changes made to either line.

I tried the =taskname but it doesn't copy the entire row details.

Any suggestions?
