Stock balance show only one warehouse

after update erpnext in stock balance we have to select warehouse and we can’t check how many pcs we have in all warehouse , there is no option to select two or more stock ,
it’s not good if we have to check each stock one by one , any other easier solution we have ?
for example any option to chose two or three warehouse and show balance of each and total balance ?

We have reverted that changes, in the next update item and warehouse will be mandatory only if you have large number of stock ledger entries (> 500000).
