Any way to change Exchange Rate Type when running valuation via TPM1?

Hi Experts:

When running TBB4 it allows changing the Exchange Rate Type (I can change from M to B)

Is there any way to do the same when running valuation via TPM1?

Client uses M as Exchange rate type which is the market exchange rate (even at the last day of each month). But they want to valuate with another Exchange Rate Type (lets call it B which has the Central Bank exchange rate used for legal purposes)

thanks in advance
