Generate a timeframe of data for one or more conditions

Requested Feature

BACKGROUND: I have been asked to generate a test patient management system. The system is supposed to allow a user to select a patient, assign one or more conditions with onsets, and then generate a health record over time from the onset dates to today and then onward at regular medically relevant cadence. Application developers would then use these test patients to test their systems.

Right now, I am implementing this in a very crude way of defining conditions and ranges for relevant parameters (i.e. A1c > 6.5 & < 8 for a diabetes type 2 patient). I want to make the medical histories of these patients more medically relevant and realistic.

It's my understanding that Synthea doesnt do a time range of data generation and doesnt allow for assigning conditions with onsets but am I read through your docs and it sounds like that is actually possible.

Before I went down the path of trying to incorporate it into my system, is there a Synthea feature for generating test patient data for one or more specified conditions with specific onset dates (For example: Patient has Uncontrolled Type 2 Diabetes and Hypertension Stage 2. The diabetes diagnosis was 1/1/2000 and the hypertension diagnosis was 1/1/2010)?

It's possible to generate patients that will have specific conditions, but as of today there's no way purely in Synthea to specify the onset date for those conditions and have the rest of the record built up around it. (I think it's a feature we'd like but we just haven't had time to implement. Related idea: #361)
The feature to specify that patient records need to have certain conditions is called Keep Modules, essentially you say "keep only patients with diabetes and hypertension" -- https://github.com/synthetichealth/synthea/wiki/Keep-Patients-Module
If you're ok with a little flexibility in the dates, I would propose a process where you generate a large set of data and then post-process to select the patients with the closest condition onset dates to your target date.
