How to add Account Number Based Lock for Indicator?

Just a remark in general:

I am frequently getting coding requests from the more "Intellectually Challenged" population of SHF. You may want to know that I loathe stupidity. I am more than happy to help with coding requests, if I can see that the requestor has done some work on their behalf, and the job is properly specified. Also, I loathe adding "some functionality" to poorly written code that is in itself full of bugs. If I can see that the idea or function that the original coder has attempted to code, is actually a good one, I would rather throw the code in the bin (where it belongs) and start from scratch.
