Can I make the VAT accounting entries follow the periodical expenses using SLA rules?

Example: I have an invoice of 1230 EUR ( invoice line 1000 and VAT 230).

Using the functionality for deferred expenses I spread the expenses over four months, 250 EUR each month.

The VAT of 230 is accounted for in the first period, but since it is non recoverable and as such is an expense, I would like to account it spread over the 4 four months as well, meaning 57,50 EUR each month.

Can this be done by using SLA rules?

Or has anyone created other solutions for this challenge?
