stitching results of two transient simulations

Hi,

This might be a simple question for those who are skilled in spectre but it seems I can't figure out how to do the following. I want to run two transient simulation, the second one starting from a point in time where the first simulation finished or perhaps at a point of time somewhere during the run of the first simulation. Then I would like to stitch together the results of the first and second simulation. I hope this is possible and going from the first to the second simulation can be done quite seamlessly.

Thanks for your help.
