I don't think there is anything that easy in the assembly level but here are 2 different ways I would do it instead of opening every part and finding the sketch etc...

1. Step 1:

   OPTION 1

   Right click the part you want to change and click "Edit Part"
   

   

2. Step 2:

   This will let you edit the part while you are in the assembly.. (Makes everything else transparent)
   

   

3. Step 3:

   Select a suitable face, and create a sketch on it
   

   

4. Step 4:

   Select "Convert Entities" from the ribbon or Tools>Sketch Tools from the menu bar. Then Select the inner diameter of the green Cylinder, and click the green check.
   

   

5. Step 5:

   It will project that circle to your selected face in that part, click OK.
   

   

6. Step 6:

   Do an extruded cut and select the region between your newly created circle and the purple cylinders outer diameter. Select "Through All" instead of "Blind" and accept.
   

   

7. Step 7:

   Return to your assembly and the purple cylinders O.D. now matches the green cylinders I.D.
   

   

8. Step 8:

   OPTION 2

   Right click the feature you want to change and click "Edit Sketch"
   

   

9. Step 9:

   Alter the value to the desired size. (1.625 to 1.500 in this case)
   

   

10. Step 10:

    Click OK, exit the sketch and return to the assembly.

    Hope this helps!
