Custom selection region

[Waning_Gibbous]

I have a few jpg's that I want to crop the same size region from each jpg.  Is there a way to input a size, for instance, 150x140?  I see there is a button to select predefined regions but it doesn't have a place to type in custom sizes.
Thank you for your time

hello and welcome,

you can add your own preset sizes by going to 'Preferences' > 'Advanced Tweaking' > 'My favorite preset sizes'. hope this is what you were looking for.
