I will try this question again here in hopes that someone has an answer so here is another go.
I use N3FJP's ACLog for contact logging. It does a nice job of bringing in the contact data from VarAC. I cho from WSJT-x, but when done from VarAC, the QRZ lookup in N3FJP is overwritten by ose the option in N3FJP to allow the QRZ lookup to be dropped in the "Comments" field. This works just fine with FT8 but seems to get overwritten by the text "QSO with VarAC" which seems to be coming from VarAC. I cannot find any way to change this behavior. See attached images please.
Nearest thing I can figure is that in WSJT-x, the callsign ony is transmitted to the logger upon initial contact connection, which allows the QRZ lookup in the logging program. In VarAC however, the contact is not started to be logged until 73 then the whole internal log line is pushed out. See image of ADIF file from inside VarACshowing the "Comment" field.
adding to my post here. I did ultimately see that there was a comment about this a long time ago with an attached image that showed a field on the settings tab for logging that allowed for auto download from QRZ and a field that had the text for "QSO with VarAC" but my settings has that grayed out. I will do a bit more digging and see if I can find someplace that VarAC does the same lookup.
Top is my settings, below is suggested from a post settings.
