Equivalent to pedal marks

[Max Karios]

Is there any equivalent to piano pedal marks for guitar? I cannot remember having seen anything. I need it for some kind of harp imitation that would be a pain to write and read in exact durations. Something like ┕━━ for the beginning and ━━┙ for the end underneath the staff would probably require a legend to make sense to anyone.

For sustain? l.v. sempre, or let ring throughout at the start, and a damp/mute symbol at the 'pedal breaks'.

I thought about a "let ring" at the beginning of the score, but it seems a bit too vague. On the other hand, I probably need to give indications on what note should be played on what string to get the harp effect of overlapping second intervals. This alone clutters the score quite a bit already. Anyway, thanks for the response. I'll try out a few things. The piece in only a draft at the moment, so I don't really know what will work best for the finished score.

What matters is that the performer knows what to do. l.v. will suffice
