Changing of default filters on panel view

1. I may be wrong, but from what I understood from your query, I have 2 answers.
   
   If you want a filter to filter the asset by end customer or contract type, you need to have those in a custom asset field. Once you have all the assets filled with this info, you can go to add a filter in the assets, and you will see the custom field option to set as a filter.

1. If your query is to remove all these standard filter options that appear op top when looking at the assets, you can simply delete them by clicking on the  filter and the delete button.

2. 

I hope it helps :) 

To add on to ​@abhinav’s recommendation above, you can also save filter configurations for quick access (just apply the filters you want and then click the ‘Save Filters’ option that appears).

Your browser will remember the filters you have applied. But if you ever clear the filter values and then want to quickly apply that saved filter combination again, you can access it via ‘My Filters’.

You can even share saved filters with others within your MaintainX organization (just select that option when saving the filter).
