Is there an easy way to mark expenditure lines for re processing when base rates are changed?

Whenever we update our base cost rate schedules (NOT BURDEN SCH / MULTIPLIERS), if we have to re-cost the prior expenditure items which are already costed? what is the best way to achieve this?

We have a large number of projects to be re processed or re-costed. Instead of going into Tools-> Recalculate Raw cost, any other way of doing this? Perhaps an update on pa expenditure items table with cost distributed = N and adjustment type = CALC_RAW?

Any suggestions would be of great help.

Thanks,

Bhanu.
