ForexTester application dll format - RSI period 5 apply to Data of RSI period 14

I'm looking for someone who can code RSI in Forex Tester Software so it can do this:

- Calculate RSI period 14 apply to Close

- Use that data for RSI period 5

It's the same as Apply to "Previous Indicator's Data" option in MT4 but Forex Tester doesn't have that option. 

I need a file in DLL format. They have instruction in https://forextester.com/forum/viewforum.php?f=9

I only have their Delphi source of RSI indicator in Forex Tester, attached all their files here.

Thanks,

Peter
