set attachment name to ${notename}-${index,%02}

[celleo]

I wonder if the attachment name style like ${notename}-${index,%02} could be supported? For example, with ${notename}=aaa, the name of first jpg image attached will be populated as aaa-01.jpg. Here the second part %02 of ${index,%02} borrows printf() formatting concept, i.e. '0' means padding with 0 and '2' is output length. If the second part brings too much programming load, a separate setting UI of "padding width of 0" along with ${index} could be leveraged.
Another potential issue is, whether to change the attachment names accoudingly once the note name changes, meanwhile the attachment folder name and link names inside the note content are changed.
