Label stacking separators - can we use a word?

[Anonymous User]

Hello all,

I'm using ArcGIS Pro 2.9.3. I have a need to create a label that stacks after the word "to". But the stacking separator only allows one character. If I use the "o" character it splits it everywhere I have an "o" (naturally) and this is not desirable. Screenshot: 

Would like to split after the word "to":

Splitting after every "o" - Not desirable: 

Also, side note: I've never gotten the "Maximum number of lines" to actually constrain the label to the maximum number of lines. Bug? 

In the above example screenshot of a label with 4 lines the settings are actually:

Thank you!

I believe that "max lines" setting is how many times the stack settings will insert line breaks. Do you happen to have a manual line break in your string anywhere?

If you need to split the label at a multi-character string, I'd insert the break into the label string itself on the Label Expression, not in the stacking sections.

var l = $feature.label_field

return replace(l, 'to', 'to\n') // or just '\n' to make "to" disappear

@jcarlson Yes, I do have a manual line break in my string - so that finally makes sense.

Thank you! That was perfect and exactly what I needed!

Another method besides the label expression that @jcarlson suggested is to use an abbreviation dictionary (translation) to add a stacking character such as a slash, then force stack on that character in the stacking settings.

Thanks @JesseWickizer! I didn't know that either.
