Is there a way to designate Slice A as "primary" instead of Slice B?

With my logging software (DX4WIN) I am required to have two slices open in SSDR (on my 6500) in order for it to work.  The only issue with this is that when one switches to a new band for the first time in a session, the "B" slice is automatically primary (yellow cursor).  Despite a couple of months trying to remember to always switch to Slice A, the first time I venture onto a new band where both slices are open, I forget, double-click a signal to listen, and OOPS, there's slice B.  I'd like the option to change this behavior to make Slice A always the primary upon initialization.  After that, behavior as usual (i.e., leave them as last set.)  I don't see any way to do that in any of the recent versions of SSDR.
