Can I store and access a data with two different sampling time (First store adequate data and the fetch with higher speed) in real time in Simulink?

I need to stora a data (real number) for entire time of simulation with 2 milliseconds of sampling time. After a certain time of simulation I need the data in FIFO mode to be used in a faster loop of say 0.2 milliseconds. Queue block of simulation does not support Push and Pop operation with two sampling rate i suppose and so can not use it. Please suggest me a solution. I hope this can be done in Simulink.
