How to align the Fiscal year with the Calendar year in Project Management (DPM)

Hello,

the calendar year (January 1 – December 31) is commonly used accounting year in the EU. 
Also our customer uses the calendar year as the accounting year.

It seems that OOTB the Budget view in Project Financials uses the Fiscal year started in the middle of some month.

We need to make the timeline columns to start at the first day of every month. (see OOTB setting in the picture ⬇️ )

Does anybody know how to make the columns (months) starting from the first day? (let say align the Fiscal setting to the Calendar year?)

The OOTB setting makes the Budgtet table unusable for us!

Thank you LV
