[Dx4win] Too long callsigns?

[Mel SM0MPV]

Hello and HNY to you all,

Is there any possibility to change the field length of the Callsign field.
As is the Canadian calls VE100VIMY/Vxx is not possible to add into the log.

I guess it is possible tho change the adif file before loading it to LOTW,
but it will not be confimed in my log if the call is too long.

Any suggestions?
