If a parameter change needs to be “locked” to a trig, then this seems like a limitation of the Elektron sequencer. A more traditional MIDI sequencer registers all data as separate events. A filter sweep on channel 1 would be completely independent of what notes (trigs in Elektron parlance) are playing on that channel in a typical MIDI sequencer.
I think the workaround is to not track live parameter changes, but rather to “lock” them to trigs and trigerless trigs.
That, or use the single LFO
