There is a way to preserve the scene tabs you had open the last time the editor was open. I'm unsure if this is what you meant, but here is how you do it:
In the editor, click the "Editor" drop-down at the top-left to open the "Editor Settings" pop-up. Under the "Interface" section is "Scene Tabs". Click that, then at the bottom of the options that appear is "Restore Scenes On Load"; check that box. Then, the next time you close your editor and reopen it, whatever tabs you had open before will be opened once again.
