Hey @richchemart. This is not possible. You can make a formal request for such a feature by heading over to the Ideate Board and submitting it to Square Online team. They will review it and make a decision about whether or not they want to add it to a future product roadmap. For now, however, I can not think of any possible workaround.
One more thing, @richchemart. Be sure to state your case. You’ll want to explain how your business works, why this is important to you, and why you can’t live without it. If you can, try to explain how you see a feature like this being something that other sellers might want and use. I can see something like this taking significant design and coding resources for Square, and they would need to justify a big change like this to online order flow.
