Convert Sample Anim BP

Was wondering if theres a way to replace the skeleton and anims within an Animation Blueprint?

For example there’s the sample starter character anim BP is there a way to replace the skeleton and anims from my own character or do I need recreate it all from scratch for my own character? I tried copy and pasting but that just leaves a stack of compile errors.

I thought maybe a retarget but my character does not show up in the selection drop down.

Another thing, so I can debug the compile errors on variables not defined is there a way to work out where a variable is defined, not just where its used?
