Your file still shows the same odd combination of the two ramp circuits, which I still don't understand.

Okay, here's the circuit modified to provide a linear ramp and hold, up or down, using two separate control inputs to stop and hold the capacitor voltage at any desired value:

The V2 /Chg input goes low to charge the capacitor, and the V3 Dis input goes high to discharge the capacitor.

If V2 is high and V3 is low than the capacitor voltage (yellow trace) is held with no charge current in or out (45s to 50s, and 70s to 80s in the sim).

Is that what you want?
