Cost Reimbursement difference due to ERV lines.

Same example to explain the issue:

There is a PO for 100 USD, functional currency is EUR.
Conversion rate on PO date is 0.8.
Conversion rate on invoice accounting date is 0.9.

Invoice distributions have 2 lines :
Item : 100 * 0.8 = 80 (functional currency value)

ERV : 100 * (0.9-0.8) = 10 (ERV functional currency value)

Both lines are imported to projects:
Item line : Raw cost 100 (transaction currency)

ERV line : Raw cost 0 (transaction currency)

Our revenue plan is cost reimbursable.
It generates revenue only for the item line 100 (for functional amount 80 : PO conversion rate).
ERV line is considered for revenue recognition.

Is there any way to recognize revenue for 90 instead of 80 ?
