    \$\begingroup\$ I think you should edit your question to indicate how it is different from the one I linked above. As you have it written now this question seems either like a duplicate or like something asking for a potentially unbound list of ways to do this. \$\endgroup\$ – Rubiksmoose Mar 25 at 18:17
