expansion replacement "-savedir $iwad/$filename/" override?

[ak1dd]

Thank you so much for the variable expansion! So in "Source Ports" I have set -savedir "save/$filename/". Works Great!

That said, I have a few wads that I play with varying mods. For example, I play one map with voxel models. I play that same map sometimes with brutal doom without voxel models.

So if I explicitly set "-savedir save/voxelplay" when I launch and I have previously set savedir with "$filename" under Source Ports I'd like it to use the dir set under Extra Params during launch to overwrite location for saves if it exists.
