I have a question regarding attaching multiple file in Task event.

I have an SMO that should get me files to be attached in mail notification of Task Event, However i before i can get the file i need to convert it first from Base64 String by using "Get File From Content" function to get the file and then attach it in the mail section of the task. (attachment 1)

If only 1 files this is perfectly doable, But the requirements is that in 1 Task Event it's able to have multiple files attached into it. Adding 1 by 1 attachment is not flexible since the attached files is random (it could be 3 or 5). Is it possible to achieve this by using the Get File function and use a List of Base64 string as the parameter? (attachment 2) is there any restriction?

I've seen many topics regarding this problem however most of them use the K2 PDF Converter and PDF Generator, while in this case both are unuseable. also Looping isn't useable either since that generates different task.
