[Dx4win] Setting the LoTW "Upload" flag for imported data

[Larry Gauthier (K8UT)]

I upload all of my QSOs to Logbook of the World (LoTW). When a new QSO is 
entered into DX4Win the Upload flag is automatically set to "Yes". However, 
when an ADIF file from my external contesting software is imported, the 
Upload flag in those QSOs is set to  "No". Without having the Upload flag 
set I cannot use the convenient "Labels -> Export for LoTW" feature of 
DX4Win (which clears the Upload flag and sets the Upload Date).

Is there a way to filter a range of QSOs (the imported contest QSOs, in this 
case) and set all Upload flags to "Yes"? Or perhaps there is a statement I 
can add to each record in the ADIF file (before import) that will set the 
flag upon import? Or maybe there is a totally different way to accomplish 
what I am trying to do...
