Here is the scenario:
We want to tolerance the stop position of an off-axis mirror system.
In other words, what we want to change is the aperture’s decenter X or Y value

we can set this parameter in multi-configuration using APDY and use TMCO to tolerance.
for example, I use the sample file in this KBA: How to model an off-axis parabolic mirror – Knowledgebase (zemax.com)
The APDY is applied to surface 2 and set tolerance between 149 to 151.
Then I open the TSAV_MIN_0003.ZMX generated by SAVE operand, we can see the decenter of aperture has been modified.
The sample file is attached for your reference.
You can find more information about the above operands in help file:
The Tolerance Tab > Tolerancing Group > Tolerance Data Editor > Tolerance Operands > TMCO: Tolerance on Multi-Configuration Data
The Tolerance Tab > Tolerancing Group > Tolerance Data Editor > Tolerance Control Operands > SAVE: Save Sensitivity Analysis Lenses
The Setup Tab > Editors Group (Setup Tab) > Multiple Configuration Editor > Multi-Configuration Operands
If the aperture is the system’s stop, set float by stop size for Aperture Type.
