Travel Plaaning functionality without integration wit AMDEUS system

Hi Experts

wel my client requirment is they want functionality which can help them sort the travel request by status tickect booked or not so that it will reduce the travel administrator work, But they are integreting wit any outside system for bookin of tickets or Hotels.

Is it possible to activate Book button in screen TP01 Travel planning???

or is there any other way to do it?

Plzz guys help me m havin hard time finding it

Thanks in advance
