Email signature location

I had asked about this before and thought I would be able to continue, however I would like to re-address the issue.

In Zoho Mail settings; personalize; signature it has a check box for:

Add my customized signature at the end of all mails

This adds the email to the end of all new emails - that's easy because the email is blank and newly created

It then adds it to the top of all forwards and replies - which is not the correct thing to do if I check the box to add to "END" of "ALL" emails

Why does it even need to have that checkbox?

Please consider having the system add the signature to the "END OF ALL" emails when it is checked, as it suggests. I really need that since cutting and pasting my signature on every forward and reply is getting old very fast.

Thanks again for considering this matter...
