Can I change my flight and hotel details after receiving my Thai eVisa approval?

Like a lot of other posters, I’m in the middle of preparing my visa application on the Thai evisa website. My question is, I’m not yet sure of the exact date I’m coming over so I haven’t gotten my actual flight yet, just want o go ahead and get my visa approved and in hand. If I book a changeable flight and hotel reservation and submit that on my application and then change it when I have a firm date, will I get red flagged if I arrive a few days earlier or later? Thanks in advance!
