Unable to Close Contract because Contract Line Funding, Invoice, Revenue do not match

We use Enterprise Contracts, as well as the PPM Projects module together. We link our project/tasks to Contract Lines. We have many scenarios where we have multiple contract lines linked to the same Contract. When reviewing the Financial Summary, the Contract level Funding, Invoice and Revenue match, however at a line level we have some lines with revenue over funding, and others with revenue under funding, this is normal and expected.

We need to be able to close these contracts where the Funding, Invoice, Revenue at Contract Level match, even if there are variances at Line level. Is this possible?
