Matching Gift Claims on Pledges

Hi! I have a donor who I entered a pledge for and he stated he will have matched by his company. We won't receive payment from him for the pledge until after the end of the fiscal year (June 30). Altru does not allow you to enter a matching gift claim without a payment. Has anyone found a work around to link these together. I'd love for the MG Claim to count for this fiscal year, but i'm not sure how to link it.
