There is a good solution for this in the latest version of @Voice, just added this (version 23.2.3 or any higher):
Open the Reading list list screen in @Voice, then create a new reading list for your novel, e.g. in this example I'll use “Evil Eye” web novel from royalroad.com. You can name the newly created list with the title of your novel, here "Evil Eye". Then press menu – Paste links, you may paste a list of links or CSV formatted lines. Or you may just paste a web address of a web-novel chapter list, like
https://www.royalroad.com/fiction/41836/evil-eye. Press Next – it shows you ALL links found on that page, so enter filter:
/evil-eye-hexcaller/chapter/
And press the filter button on right – now the list will contain only the chapters you want. Press Next again and then select or create an empty folder for this web novel. Press Import Links button. You’ll have all your chapters on one list.
When it’s time to update with newly added chapters, simply press Reading list menu – Paste links. All the data will be remembered there (the web address of the chapter list, the filter etc.), so press Next, Next – on the last screen make sure that “Skip links already downloaded into this folder” is checked (it is by default), press Import Links button. The new chapters are added.
