Is there a way to block complete transaction ?

We have a specific requirement. In fact, we have many users making transactions, and in a particular situation, they must enter a specific memo line that they always forget.

So the request is: when the transaction is greater than a certain amount and a specific VAT code has been used in the lines, check that this memo line is present among the lines; otherwise, block the completion of the transaction and show a message.

Is it possible to include this type of check or something similar in the standard system?

thank you
