Enable Pre-order in bulk for variations

Hello.
Thank you again for this amazing plugin.

Is there a way to enable the pre-order feature for all variations inside the product editor?
For example, I sell shoes and I have 10 size variations. In order to enable Pre-order feature I have to open each variation to enable pre-order. That’s ten times.

Is there a way to do that please?

Thank you again
