[Dx4win] Hw to change?

[wo2n]

Hi, Tnx for reading this:
Hw can you change ONE QSL mgr route, without having all the other QSO's in 
the log change?
In other words 3 different mgrs,or mail drops. for same call?
Reason, old qso, and three different sauces are found, so I want to send to 
both.
Grateful for all replies

PS 2 different mgrs show in data base for the callsign, yet changing one qso 
changes all?
Oh call is EZ8CQ
