Gui for Tallent Management infotypes in ECC

Hello

Doing first steps in implementation of Talent Management.

EP not yet prepared, meanwhile I want to prepare some steps in ECC.

My environment is SAP ERP 6.0 with enhancement package 4.

Trying to maintain some infotype: (7407-Career Goal, 7408-Potential, etc..) I wonder where from to maintain them.

Should I customize PP01 with new tab for those infotypes or there is a more sophisticated mechanism/Tcode.

Regards

Zeev.
