Standard Price Batch and Entry, extend ranges

[DannyC]

I'm needing to extend the ranges for the 2 Price Update screens, Standard Price Entry and Standard Price Batch.

Need from/to Price Groups.

I can add in the from/to with an extra column for them to manually type in values.
But when the UltraButtons are clicked I'm stuck knowing how to pass the values from the grdRanges to what Jiwa is doing. Looking at JustDecompile I can see LoadFromRanges() but not sure how to modify it to use the extra parameters.

I also need to add the Price Group column into the Standard Price Entry grid.

Attached is my plugin so far. Would really appreciate a heads up on how to get this going.
