Reloading part exposed film.

Recently, I had a rewinding problem with my Espio120 and it has been repaired by Pentax and is back to full working order.
The camera had been rewinding the film after exposing just a few frames.
The 120 (and my 280-P) offer mid-roll rewind but is it possible to reload and continue using the same film in either of these cameras?
I also have an SFX and a Z1-P and I know that the procedure with SLR's is to reload, select a manual shutter speed (flash sync.) and with the lens cap attached, fire the shutter until a frame or two after the last exposed shot.
Is it possible to safely achieve the same thing with a compact?

I have one 36exp. film that I wish to complete (only 6 frames exposed) and I really don't want to lose those shots or pay for processing 30 blank frames.
Should I just use one of the SLR's?

Thanks
Kimbo.

Hi Kimbo,

If you are unsure how to do it with the compacts, I think the easiest and safest way is to continue using the film on one of your SLRs where you are most comfortable reloading a half-used roll of film, unless you really wanted to shoot with the compacts with it.

That's just my opinion Cheers!

Thanks ShotGun,

I think I'll use the SFX, it's the only one currently not loaded with film and it'll be nice to pull it out of retirement - I've not used it for ages!
Didn't really fancy the idea of covering the lens on one of the compacts anyway.

Cheers and a Happy New Year to you.
