Can I keep filing multiple returns on the same day if I failed to check the "will you be using NETFILE to submit a prior year federal return, today or within the next two days?"

Can I keep filing multiple returns on the same day if I failed to check the box beside  "will you be using NETFILE to submit a prior year federal return, today or within the next two days?" on the first return I sent today.

In other words - I have filed our 2020 returns - but - I failed to check the box related to  "Will you be using NETFILE to submit a prior year federal return, today or within the next two days?"  Can i still proceed with filing 2021, 2022, 2023 today?

Thanks.
