does the boss rc50 have insert modes similar to the edp?

[geoff smith <geoff.smith97@virgin.net>]

I have watched both videos for the rc50 but haven't seen any use of any 
insert functions, I remember reading in someones post that there are 
various 'overdub' modes does the rc50 have an insert replace and insert 
substitute function like the edp,
I would really like the one that works by inserting something the next 
time round a loop can't remember which one that was called as I sold my 
edp a while ago.
cheers
