Not sure how you would import it to overlay, but open tree up in xl,sequence and expand it to strand level, you will than have to expand the strand to node level and then copy and paste the effects
it doesn’t appear that you can copy a strand row and then paste it onto another strand.
If you import the sequence maybe you can tell it to,add the effects to a different set of strings on the tree?
Cheers and good luck Boof63
