How to embedd "Harvey Ball" (symbol) in a cell

I would like to embedd a symbol into a cell. I dont want it to be done by using Fonts. By symbol I mean Harvey Balls (Plan, Do, Check, Act) symbol embedded the same as the "and" (&) symbol. I have seen it done once on a spreadsheet but did not get a copy and I would like to recreate it as a way of visually showing the status of an action item.

Thanks
