Hide oscillator trendlines from other symbols

Please. A formal request for something that has been mentioned a few times. Please only show trendlines drawn on oscillators for the current symbol.

For traders who draw divergence between oscillator and price, it is extremely difficult to trade when trend lines from many other symbols remain on the oscillator as the trader switches symbols.

Right now I have trendlines on my oscillator from 4 different symbols. It is a mess, and I can't tell which trendline applies to the symbol that I am currently trading.

It gets much worse when the trader jumps between symbols and time frames, example: trading 4 symbols x 2 time frames = potentially 8 trendlines visible on the oscillator.
