Modify an existing MTF Fibo indicator

I have an existing MTF Fibo indicator that I would like to add some feature

I want a flag to include the RSI if I want to with trend lines

I want to specify the RSI properties like color and period as I don’t use the default

Use RSI -> Yes/No

If I say yes I would like to add vertical lines from the last two swing highs and last two swing lows down to the RSI and connect the highs and connect the lows as trend lines on the RSI like in this picture below.

I would like to set the line properties on the lines the same way as other trend lines

Colour/Width/Type etc
