Is Specify Tax-Determinant Values coming to Requisition Summary/Header level?

Summary:

in 24D Specify Tax-Determinant Values While Shopping was introduced. However you can only change the tax determinants by going into each individual line, this isn't really viable and can lead to mistakes if there are a lot lines. I couldn't see the option to enable in VBS when editing the requisition on a summary/header level. In Classic SSP you can edit all lines at once and individually.

Is there someway to do this or is it coming in the future where you can go into the requisition summary and change the tax-determinant, it makes sense there also as you can change the charge to and budget code there too and override all lines.
