Is it possible to write shortcodes with complex logic?
I want to transform template like this: `{{< t 59a12b >}}`
to
```auto
5a
9a
1b
2b
```
Is it possible to accomplish with shortcodes? I wasn’t able to figure out how to do it.

I forgot to mention, that input string can by any number of characters, so it could be `1a419b`, `1123a3b`, etc.

Your goal is unclear.
