Help with calculate the total sum of record in column one

Input file:

Code:

101M
10M10D20M1I70M
10M10D39M4I48M
10M10D91M
10M10I13M2I7M1I58M
10M10I15M1D66M

Output file:

Code:

101M 101 0 0
10M10D20M1I70M 100 1 10
10M10D39M4I48M 97 4 10
10M10D91M 101 0 10
10M10I13M2I7M1I58M 88 13 0
10M10I15M1D66M 91 10 1

I'm interested to count how many total of M, I, D at column one and output it at another file.
At the desired output file, first column is the original raw file record and second column is total number of M in column one, third column is total number of I in column one and forth column is total number of D in column one.

eg. 10M10D20M1I70M can be interpret as 10M 10D 20M 1I 70M. So the final desired output is 10M10D20M1I70M 100 1 10
10M10I13M2I7M1I58M can be interpret as 10M 10I 13M 2I 7M 1I 58M. So the final desired output is 10M10I13M2I7M1I58M 88 13 0

I can't think any idea to calculate the sum of M, I, D at column one by using awk, perl one liner command yet.
Thanks for any advice.
