Export excel number format align with Anaplan data format

We have lineitem set as number with 2 decimal places.

We set export file action with excel format template for user to easily upload back to the system. 

The excel output does not set data format by column but by cell which making us lost decimal number if we did not change format to number.

Cell that already has data entered:

Cell without any data:

Any cell with "Number" format, even we enter x.xx. It always show rounding number.

Once we save as CSV or Tab we lost number. We expected to save exact value not a rounding value. It would be good if Anaplan can set the excel output with the proper format since we already identify that in the lineitem.
