Number Sequence
Generate a sequence of numbers and apply it to a tag — perfect for filling out Track Number.
The Number Sequence function sets tag values to a generated sequence of numbers. You can also add the sequence to an existing tag at any position. The sequence increments once per selected file — if you have 14 files selected, the sequence increments 14 times. This function is especially useful for quickly filling out the Track Number tag.

Actions
Set Number Sequence — Set the value of the given tag to the number sequence, replacing any existing values.
Insert Number Sequence At Beginning — Insert the number sequence at the beginning of the given tag's value, before any existing value.
Insert Number Sequence At End — Insert the number sequence at the end of the given tag's value, after any existing value.
Insert Number Sequence At Position — Insert the number sequence anywhere within the tag's value, at the given position.
Options Explained
Tag — Which tag to apply the number sequence to. Any tag is supported.
