Bom MASS Change function to include additional BOM fields

When updating boms via add, substitute or delete functions, there is very limited amount of fields that can be used to populate and complete the BOM entry. 

For example, 

• Position did not populate correctly, 
• There is no ability to mass update the I-Version selected in the BOM
• You cannot set a default backflush warehouse
• You cannot set a default routing position

Therefore, when updating a companies BOM, if they use any of these fields above, you still have to enter every BOM and update, OR perform a DIH upload. (2 steps) to mass change BOM values. 

The mass change functionality could be an end user friendly option, without the need to use DIH if it has this functionality to update the default commonly used fields.
