Two different instrument methods in one run sequence for Agilent GC headspace

We have problem in using two different instrument methods in one run sequence. Used Empower and headspace model G1888 and GC HP6890. We required to change Headspace oven temperatures during the run from 70°C to 90°C. Std-A required a Headspace oven temperature 70°C, while Std-B needs 90°C. Is there any option in Empower setting to resolve this issue?
