Need to read ExponentialBackoffRetry values dynamically instead of hardcoding in host.json or inside the annonation

[rohan-roy5]

I have implemented Retry Mechanism in Azure Function using annotation ExponentialBackoffRetry

@FunctionName("testFunction")
@ExponentialBackoffRetry(maxRetryCount = 5, minimumInterval = "00:00:10", maximumInterval = "00:01:00")

However now we want to make ExponentialBackoffRetry parameter values configurable instead of hard coding as above.
We are unable to use the host.json as there are multiple functions in one function App
Is there any way to achieve this?
What we need is something like below
@ExponentialBackoffRetry("%maxRetryCount%", "%minimumInterval%", "%maximumInterval%")

Any updates on this if possible? Is this an existing issue or am I missing something?
