Help! I need to merge two shaders!

[Crian]

Hi guys, I would need to merge two shaders together so that I have one shader with both functions.
Basically, I need to flip an object and, on certain occasions to add a hole to it.
The shaders are:
- Flip (Complex-softwares / Masks)
- Hole (Shader pack / Effects)
Could someone be so kind as to help me?
Thanks in advance.

Well, some shaders are quite simple to combine, while at it, I did a small optimization.
