KPI with periodicity bimonthly and semiannual

Hello,

In our implementation we have KPI with periodicity bimonthly and semiannual. We want to know if it is possible to have this filters en the Scorecard.

If is not possible to do it, we want to know if is possible to do a customization SSM.

We have SSM 7.5 SP 12.

Thank you very much
