Continue transient study step from last time step

Hi everyone,
I am trying to divide my transient thermal study in three steps, as each one requires a different tolerance (for correct simulation) and number of output times (for correct plotting). The three solutions need to be concatenated. The "Combine solution" step serves the purpose, but not well enough as it doesn't connect them correctly if their ranges overlaps. From the documentation, this happens because the "Combine solution" step resolves overlapping ranges by only keeping the first solution.
The problem is that the different steps are stopped by "Stop conditions" so they never fully complete their ranges and then it is not possible to tell a priori which are the first and last time of each transient step. If I give a time margin, what happens is that the "Combine solution" step combines the different solutions by adding wide plateau between them. Is there a way to automate the process (i.e., having step-2 take as first time for its range the last time of step-1 and etc.)?
Thank you

Unfortunately the command seems unsuited to my case. Nevertheless, I found an alternative solution.
