Description
For most systems, there will be exogenous input signals as control inputs/disturbances, such as the outdoor air temperature.
Say I have a zone temperature file saved as a csv, and the temperature is sampled every hour. But I have a system, which runs at a time step of 5 min. How can I connect this exogenous temperature to Thermal.PrescribedTemperature, and solve the resulting ODE on a 5-minute basis?
In Modelica, there is a block called TimeTable, which performs auto interpolation between time indexes. Is there any similar block in ModelingToolkitStandardLibrary for this purpose?

Research direction
No file or test is named. Start by locating the library's source or input-signal components and compare their behavior with Modelica's TimeTable, including interpolation from hourly CSV data to a five-minute simulation step. Done means a documented or implemented way to connect the exogenous temperature to Thermal.PrescribedTemperature and solve the resulting ODE.
