Hi Robert, unfortunately, I don't think that would be possible.
With a regular button/switch press using interrupts, firstly an interrupt happens (ie when the switch is pressed), then in the interrupt routine the rogram just rechecks after a short while to see if the same condition is held.
But with capacitive touch, you have to exit the interrupt routine in order to get the next 'timebase' (the timebase here being 'time' between a timer based based interrupt - & is used to count the output from the CPS module), in other words you can't hang around in the interrupt routine to see if the condition has held.
