Excel Looping With Bloomberg And Pause

I have an excel workbook right now with a 75x75 correlation matrix. It has 75 stock prices and uses bloomberg to pull in the correlation between each of the holdings. There is a lot of data so it takes roughly 35 seconds for it all to get pulled in from bloomberg. The input value that I can change is the date. The output value is a specific correlation coefficient. Thus, if I input today's date into a cell in the file, it will run the correlation matrix and tell me the correlation between all the holdings using the past year's data. Then it will produce a single output value.

I am now looking to use VBA to make this more robust. What I have been trying to do is have a macro which will -

(1) input the current date into the input cell
(2) have the code wait 35 seconds (and since it is using bloomberg pull in the traditional wait methods do not work because they actually stop the data pull in also)
(3) copy the output value
(4) paste special that value in a different cell
(5) repeat the process but this time use the date from a day before and have the output value copied and pasted to a cell below the previous one.

This loop would continue over 20 times.

Below I have some code that allows me to do this process once but is not looped and I have been stuck trying to make this work with a loop given the bloomberg delay. When I add a loop, it does not wait the 35 seconds I need before doing the whole process again.
