First: having a custom init patch is very handy! Always starting from an init sound with open filters keeps frustration about patches sounding different when reloading them away.

The feature i use is: When you open the load patch menu or the save patch menu, the cursor will jump to the last used slot. So maybe you can adopt my workaround:

Create an init patch and save it at a prominent place (for me this is patch slot 0) with a good name. “init” may be a good choice. Before you start jammin, load the init patch on one track. Then start playing around. When you now press - you just have to press twice to return to your init sound.

Indeed this is the double amount of klicks, but it will be in your motoric memory very soon.
