Not in VFP 5 (don't know about 6). The best I could suggest is have a property in an App object to track this.

In the App class
oApp = creatobject("AppManager") && whatever
oApp.DSIDs = ""

In form class Init:

oApp.DSIDs = oApp.DSIDs + ";" + padl(This.DataSessionID, 3, "0") && pad with zeros

In form QueryUnload

oApp.DSIDs = strtran(oApp.DSIDs, ";" + padl(This.DataSessionID, 3, "0"), "")
