2/4 time

Hi all. This is my first post. I mostly seem to use the standard set on blues 2. It’s the most universal best I can find for my songs. Some of my songs have a slow feel (the beat may actually be 160bpm, but this is too much drumming so I set it for 80bpm) and I find setting the BB to my usual setting makes the timing of the transitions etc wrong (too long etc).

To your knowledge is there a 2/4 time signature? I can’t see it in ‘odd times’ as this might solve the problem. Any idea how I can remedy this?
