How can I make PulseEffects apply presets to certain devices that are currently broadcasting?

Question

linux

Elementary OS 6 Odin (based on Ubuntu 20.04)
With grief in half, I learned how to more or less adjust the sound in my laptop using PulseEffects, I found my own presets for each device (for the built-in sound and for the Bluetooth speaker). But:
1. When changing presets, the settings are not automatically cut (ie, you have to manually activate the equalizer, compressor, etc. in the PulseEffects menu). How to fix?
2. How to assign a different preset for each of the two devices? In other words, what needs to be done so that when connecting and disconnecting the speaker, you don’t have to go into the PulseEffects settings and do everything manually (change the presets back)?
