Web Clock: Fetch location attribute in dynamic URL

We are trying to create new page entry on homepage which will dynamically select Location's attributes and accordingly display the result.

Example - we have one static URL which will display Web clock, now based on location entered in fusion application for that specific employee it should display result-

 Link is static until word UnitID= in URL https://AbcCompanyApp.ABCinc.com/RWS4/WebClockLogin.jsp?UnitID=W95008

* From the URL - W95008 - Dynamic

* W- stands for Warehouse/DC, likewise we have Corporate - C, S – Stores, need to derive based on the location table attribute1 ?

* 95008 – Dynamic is the first five digits of Location on Assignment Screen, this changes for everyone depending on their location.
