When you want to assign a estimate or invoice to an existing ticket, you click on Edit and then click on the drop-down list to choose an existing ticket. Some of my customers have hundereds of tickets and currently the existing tickets are not in any logical order and it is near impossible to find the correct ticket. If this could be a searchable field or at the very least placed in numerical order it would make this process way faster. Many times we duplicate similar estimates when presenting the customer multiple options but need to assign the duplicated tickets to the same ticket which is when this issue arrises.
