modifiable production-ready software for Renesas Synergy products?

Hello,
Regarding Renesas Synergy platform/products: does anyone know if the production-ready software is easily modifiable for specific products?
I'm new to this particular platform; I'm using the S7 Starter kit.

Thanks

Too vague...

The RL78/L1x is quite rare... I've never seen a user here that uses this platform... When choosing a platform it's wise to check the global community.... Pic or ARM and you are laughing... Renesas do an ARM platform with cortex CPU's.. This may have been a better choice...

When I started, as I was at Portsmouth Uni and we used phillips G4 and S4 16 bit.. Guess what!!! No one else did... So I moved to Pic...
