Click To Copy Cell Within Range To Destination Cell?

My goal would be to click on a cell within a range of cells (in a column) and have the value copied to a specified destination cell. There would be a few different columns with source cells and two destination cells. Each column would to copy to a specific cell. My ojective is basically to deal with different processing times (days, weeks, months).

Here's a little visual, clicking on C4 for example would copy the value "5" to cell B2. Clicking on D4 would copy "12" to A2.
