Modifing wooimporter plugin for woocommerce

I am using woocommerce on wordpress musltisite for my ecommerce sites. I am using Wooimporter to import products from Aliexpress and Ebay. The its works fine but I need to modify the search result which has been found and divided max 40 products per page up to 10240 products divided on 256 pages that is for Aliexpress. For Ebay is the same but the result per page is max 100 and the total of the results is up to 10000 divided on 100 pages. When I import the I cant select them all at one and import them. the problem here I have to select the max per page and wait until the products has been imported and than go to the next page and repeat the same process again. Its time consuming for me and I need to speed up the importing of the results. 1- need to modify the script to select all the found results for Alexpress is 10240 and import them at once that is will be for Ebay the same 2- I need to add multi threads php to the script because it works very slow and I have to import a big amount of data. The script is PHP so you need to have a good knowledge in Woocommerce and also plugins in general. Bidding is $50 MAX all bidding above will be deleted I am attaching 2 images for both result Alexpress and Ebay as well
