How to dump custom schedule to EnergyPlus library

Hello friends!

I have a simple shoebox model at the moment, trying to simulate the effect of some specific radiative materials on the roof. so I calculated the emitted thermal power for my roof surface and now I want to apply it using EP SurfaceProperty:HeatBalanceSourceTerm component as an additional string to my idf.
To do so, I created an hourly schedule of the thermal power. However, when I try to add it as a string, It doesn’t work since my schedule is not in the EP library.

so is there any way that I can add this custom schedule to the EP schedule library? (not to the HB energy standard library)
or any other ideas?

You can also add schedule as string to Run IDF.
