Present field results in columns and rows

I have a formula that checks a number of different summaries to ensure that all "required" fields are completed.

It lists the fields vertically if they are missing data.

However, the list is quite extensive and causes the form/row to be quite long at times.

Is there a way where instead of presenting each item in a single column with X number of rows, I can make the results populate into 2 or 3 columns by X number of rows?

My current formula (truncated) is this:

var text Exceptions =

List("<br>",

If(Trim([Client Name])="","Work Order Missing: Client"),
....
....
....
If([Total # of Assignments Missing Notes]>0,"Assignment Missing: Assignment Notes")
);

If(Trim($Exceptions)<>"","<font color=Blue><b>Below is a list of fields that are missing data to move the Work Order to an Active status:</b><font color=Red><br>"&$Exceptions)

Is there a way where instead of

"<b>",

where the break comes after every comma, I can make it come after every 2nd or 3rd comma?????

Also, kudos to Mark for helping me with the formula!
