Excel-Macro to sumup data from multiple workbooks to Master xlsx

Hi All,

Can you please help me.
Scenario:
1. There is a common template which has some tasks listed in columns against which the team members will update the time taken (effort) for each task in the entire month.
2. There are different levels of team members (Entry, Intermediate, Specialist, etc.).
3. The template has multiple sheets, but all the sheets have same template.
4. The template has the common tasks listed in the Columns (Say A25 to A156) and on the rows there are these levels mentioned under which depending on his/ her level, the team member enters the time (effort) for each task [so if he/ she is and Entry, they will enter values (Effort) in B25 to B150 cells]. There are chances that the cells can be empty for few of the tasks also. The Range may vary, so in the solution it would be helpful if I get an option to enter the range that I want to consolidate.

Example
Tasks SPE INT ENT COR
Task 1 2
Task 2 4
Task 3 5
Task 4
Task 5 12
Task 6 22
Task 7 1

5. Each of the team member submits one excel work book with the entries for the entire month based on his level, so I will have multiple such work books in the name of each team member.

The need:
I have a master file which has the same tasks listed in columns and same levels mentioned in the rows (rather the same template). I need to consolidate by adding the data from multiple cell ranges (say E11:F13, E17: F18, D25:M165). The below code is currently doing only for one set of cell range.

A macro with the following would help:
1. An option to select multiple excel sheets rather than path hardcoded.
2. If there are entries in other sheets (P2, P3, etc) consolidate the same in the respective Master sheet (P2, P3, etc).
3. Everytime I run the Macro, it has to wipe previous values of the cell and consolidate.

Currently I have the following Macro:
