duplicate program check using CONCSUB

Hello,

I'm looking for capability to check for an existing scheduled concurrent request with matching parameters before submitting a repeating concurrent request using CONCSUB. For example, I should be able to schedule a concurrent program A with parameters x, y, z to repeat at time t, only if this program is not already scheduled with the same parameters.

Do I have to write my own logic to do that check or is it in-built in CONCSUB or FND_SUBMIT APIs?
