Concatenate waves in different data folders

Hi,
I have some data in different data folders, organized in waves that reference which time the data point was taken during an experiment.Each data folder contains data from a different experiment, and data points may or may not be at times similar to time points taken in other data folders. I would ultimately like to merge all of these time points together into the same data folder, and organize the data into waves based on what value of T the point was taken at. That is, one data folder might have 4 data points in waves corresponding to 0, 50, 100,200, and 250 sec and another data folder might have 6 data points but only at times 100 and 200 and 300 sec. I would like to merge these data together to ultimately give waves for times of 0,50,100,200,250 and 300 with 4 points in 0,50,and 250 and 10 points in the waves for times 100 and 200, and 6 points in wave 300. I know i can use concatenate to merge waves, but concatenate only takes wave references and not data folder references. Can I use concatenate to take waves from Folder a, b, and c, and merge them into a folder elsewhere and combine the data if there are data in waves of similar names??

Please let me know if this is confusing so i can elaborate further

thanks,
Phil
