campaign strategy

I just got sh4 the way I want it I think. It is patched to 1.4; I have a small cheat and RSRD installed. I thought the stock version had too many contacts. It seems like all I run into are single ship contacts. Aren't there any convoys in RSRD. it is the latest version fpr 1.4 I think. Is there any adjustment that can be made to increase convoy contacts. I am playing in mid 1943, I like the realism involved but wish I couild run into more action. Thanks in advance Brian
