More than three attachments in mass distribution of emails

Hello,

Thank you for adding the new functions of Creating Mailing List and Send Emails. They are very useful to me.

My question is as follows: Is there a way of attaching more than three attachments, or is it limited to only three attachments. And if it is limited to only three attachments, is there any plan to expand this further in a later version?

Regards,
Fredrik
