Solution Update - Study modification

Hi All, I have a basic question. I am simulating some mechanical structure in frequency domain for example between 100Hz and 150 KHz, and I want to extend my solution from the previous interval to 100 KHz to 200KHz without solving for the entire range. can I add the 50KHz range to the previous solution ? Or do I have to re-simulate the structure by using the updated interval from the beginning?

Thanks!
