To Override Project Coding Mask

Dear All,

At present, we have coding mask in system where the Project ID= Company code

For example For ABCD Project ID , coding mask is -XXX-XX-0000-XXXXXXX, and ABCD is also a  company code.

The new requirement is to have Project Def such as ABCDP0001234, without any special characters, where ABCD is company code.

How can I override the existing coding mask for creating new Project Def, for say, a new Project profile.

Is there any user exit available for this?

Regards,
