Scraping from point to point

Hello everyone,
First of all, i really like this scraper, but i have problem with it. Tried to scrape emails and company names from info website and firefox crashed, i got big part of data, but i want to resume and released that its impossible. Unfortunately scraper starts scraping backwards. And right now i am only able to collect remaining data is to start over. Is there any way to start from top ( "advokatai" ) to specific part ("metalo laužas")? Or if scrapper starts again from bottom, then from specific part ("metalo laužas") to top ( "advokatai" )? There is my current sitemap and i'm not able to figure this out :confused:

Url: https://www.info.lt/veiklos/pagal_abecele#A

Sitemap:
{"_id":"infoltnaujas","startUrl":["https://www.info.lt/veiklos/pagal_abecele"],"selectors":[{"id":"Kategorijos","type":"SelectorLink","parentSelectors":["_root"],"selector":".list-unstyled li:nth-of-type(n+2) a","multiple":true,"delay":0},{"id":"Pages","type":"SelectorLink","parentSelectors":["Kategorijos"],"selector":"a.puslapiavimas_a","multiple":true,"delay":0},{"id":"Imones","type":"SelectorLink","parentSelectors":["Kategorijos","Pages"],"selector":".info a[data-marker-id]","multiple":true,"delay":0},{"id":"Pavadinimas","type":"SelectorText","parentSelectors":["Imones"],"selector":"h1","multiple":false,"regex":"","delay":0},{"id":"Emailas","type":"SelectorText","parentSelectors":["Imones"],"selector":".col-xs-8 a[data-stat-type='6']","multiple":false,"regex":"","delay":0}]}

Hi you can use nth-of-type ranges for this. For example
.list-unstyled li:nth-of-type(n+2):nth-of-type(-n+7) a
will select only the first 6 items. You can use Element Preview to see what the range selects.
