Conditional field for File Attachments

Hi Guys,

Is there any way to add conditional tags in FILE ATTACHMENTS section?

The conditional tags are working perfectly in Message Body, but not working in FILE ATTACHMENTS.

Eg:

[group-spanish]
uploads/2018/08/spanish.pdf
[/group-spanish]
[group-english]
uploads/2018/08/english.pdf
[/group-english]
[group-malayalam]
uploads/2018/08/malayalam.pdf
[/group-malayalam]

These conditions are not working in file attachments. All the files are being attached and sent to the receiver.

Is there a way to use this conditional fields in File Attachments?

Thanks and Regards,
Rejin Jose.
