Create Dynamic Child with sequential code

Hi,

Can we create sequential project codes in EPM metadata?

We know we can use the Create Dynamic Child option to create metadata members through RTP. In this option, we manually provide a member name. I want to use this functionality to create new projects which means that project codes should be generated in sequential order as Text (not as number format). The problem with the number format is that after "999", it will start adding commas e.g. "1,000" which does not appear like a code for end users. In addition, we might want to include some alphabet prefixes e.g. PR-0001. That's why, the Text format is required.
