There's no alternative for what you want to do.

There is an alternative, but still is not a ideal solution.
You can add binary field and onchange method.
Once the file is inserted into binary field, you can, in onchage method, convert it to attachment in many2many field, and clear binary field to be able to add next file.
It doesn't solve the problem, it's just workaround.
