Tracker help Blank Title 56429

Have not done much with dashboards and trackers - yet.
Maybe some kind soul can help....

(running 8.00.811a) On the Financial Management -> Accounts Payable ->
General Operations menu is the Posted Transactions tracker. I have had
a request to add a search to lookup vendors to the tracker.

If this is possible, could I get some pointers on how to accomplish?

Many thanks,

Bernie.
