Split the PR line for two or more vendors

In AX 2009, is it possible to Split the PR line for two or more vendors while creating the Purchase order ?

For example, item 1101 have 100 quanities in PR line. While creating PO from PR, to reduce the dependency on the single vendor, i would like to create two purchase order for 50 quantities each for two different vendors i.e. 1001 --- 50 quantities & 1002 ---- 50 quantities. ?
