Actually, if you haven't bought the MPC7 yet, you can buy it as one combined SKU: MPC7EQ-10G-RB.
If you have the MPC7E-10G-RB already, you need to order this license on top: S-MPC7EQ-10G.
The MPC10 BOM looks like this:
MPC10E-10C-P-BASE
S-MX-10C-P1-P
+ support:
SVC-COR-MX-10C-P1P
SVC-COR-MPC10E10C (or CP/ND/SD depending on your needs)
