Been mucking around with the Pentax 360 flash, and came to the realisation, that the camera does not allow wireless mode when using manual lenses (which happen to be 4 out the 6 lenses I have)

This makes using these lenses next to useless if I want to use the flash wirelessly.
How hard would it be to allow the user full manual controll of the flash in wireless mode??? Maybe the boffins at Pentax think we are not capable of working manually anymore.
Just wondering if anyone knows of any other method , apart from radio triggers to get round this?
Cheers.
