Not 100% sure what you mean. The UK CAA does not issue P2 ratings etc, so it'll be unrestricted when you have it added to your licence.
If what you mean is that your Dash 8 type rating is co-pilot (p2) only on the ICAO FAA licence then you need so continue reading Section F9 and ignore section F9.1 - as this is to transfer from a PIC rating. F9.2 is for someone holding a P2 rating.
F9.2 TRANSFER OF CO-PILOT ONLY MULTI-PILOT TYPE RATINGS TO PILOT-IN-COMMAND RATINGS
It is UK policy that all new multi-pilot type ratings included in a UK issued licence will be unrestricted Pilot-in- Command ratings. This is based on the fact that all pilots are trained and tested in the role of Pilot-in-Command.
Therefore, applicants wishing to transfer their Co-Pilot rating to a UK issued licence will be required to meet the following requirements:-
Transfer of co-pilot rating from non-JAR-FCL licence
The applicant must:
1. Produce evidence of having a valid co-pilot rating within non-JAR-FCL licence.
2. Meet the requirements of JAR-FCL 1.250/2.250, including theoretical knowledge requirements.
3. Complete the type rating training at the discretion of the Head of Training at a JAA Approved TRTO.
4. Pass the course based theoretical knowledge examination.
5. Pass the skill test.
Hope this helps.
