It is perfectly fine to split the funds into multiple FDs or even multiple Bank accounts as long as you are the Primary holder of that account.
And Reference Letter/Roles and Responsibilities letter is of utmost importance. You will need to get your roles and responsibilities letter designed/crafted as per your NOC. Just google for NOC code and you will get the standard NOC code responsibilities, then build your reference letter accordingly.
Like for IT people most common NOCs are 2171,2172,2173,2174..
