Combine Two Macros For Dropdown Boxes

I have a spreadsheet I use to track reprimands for our employees. Reprimand Counseling Spreadsheet Example.xlsm. Previously, I had to read the entire reprimand in order to determine the policy violation(s) and then manually enter those reasons into the cell. We have a new standardized form, where the manger selects the reason(s) for the reprimand. I wanted a drop down box that I could select multiple reasons for the reprimand and have all the reasons appear on the same line, as well as being able to remove a reason from the line by selecting it again (so I wouldn't have to start over, in case I selected the wrong reason). I was able to find this code, on [URL] .... to accomplish that.

Same Cell Add & Remove

I also need to be able to manual edit some of the reasons. For example "Missed Meal Period(s) #___". I will need to be able to edit that item to read "Missed Meal Period(s) #2". I was able to find this code, on the same website as the previous code, to accomplish that. However, this code includes a line break, which I do not want.

Edit Same Cell

[Code] .....

Since I need the code to work on each worksheet (CIVI - SOCR), will I have to enter the code on each worksheet or is there a better way to accomplish this? Is there a way to combine these two codes, while simultaneously removing the line break? I need to select multiple reprimand reasons in the same cell and edit the reasons, if necessary. I've read and reread that article for hours, but I can't get it to work.
