If I am understanding what you are asking, I don't see a way to change a place count from "1" to "11" for a single "checkmark". What you could do is create a custom column and set it as a formula with the expression "Count * 11". I tried this with six checkmarks on a sheet (count of 6) and in the custom column in said "66". Then I "Split All" on that count and got 6 entries in the markup list all with a count of "11". If I just place a single mark with a count of "1" - it reads "11" in the custom column.
Does that help?
