Excel 2013 look for a string and if found copy the cell to another cell

I have 4 Tabs in a workbook with the exact same first 4 columns in 3 of them.

The first 4 columns of each tab are

User / Hidden / Case number / Date In

The Tabs are

 Internal / NT / External

There is a Tab called Case Number

If any cell in column C from any of the 3 tabs starts with SC I would like it put in the next free spot under SC in tab 'Case Number Tracking'.

If any cell in column C from any of the 3 tabs starts with RW I would like it put in the next free spot under RW in tab 'Case Number Tracking'.

Please see attached picture as it will help explain

This is the columns and tab names

Internal!C:C

NTI!C:C

External!C:C

'Case Number Tracking'

Thanks!
