It's enough of a stretch for me to do this as it is, let alone trying to figger out how to add that in place

Or alternately the lazy man's approach to setting up one of those regs: use a pot in place of the two resistors, set it for max output voltage, hook it to the circuit with a ~100K ohm dummy load and cap on the output, meter the output and adjust the knob till you have what you want....So easy a grade-schooler could do it.  If you unlock the mysteries of these regulator chips and have usable scrap power transformers and passive components around you can make virtually any power supply you want, and as many as you want...

I'd use something this, and convert the 5U4 to silicon diodes:
