Approval policy that allows to change lease time and cpu count

[bdamian]

I could create a "Service Catalog - Catalog Item Request - Composite Blueprint" approval policy that allows the approver to change the lease time.

I also could create a "Service Catalog - Catalog Item Request - Machine" approval policy that allows the approver to change the cpu count.

Is there any way to create an approval policy that allows the approver to change the lease time and the cpu count?

I can add custom properties to the approval policy, but they are shown as text and is not suitable for cpu count.

Thanks,
D.
