[Trlog] LOTW Question

[K4LTA]

Recently, I have joined LOTW hoping it will reduce my QSL chores. So far, I only know how to upload a CBR file after converting it to a TQ8 file which is required.  I am using TR 679 and I find no way of making a CBR file from my General QSO file that I use for my daily logging. TR says too many dates for the contest.  Can someone advise how to get around this problem? Would a later version of TR log help? Thanks
